It has been a long and exciting journey as we reach the homestretch of this project. What started out as a question of whether or not a green roof on a warehouse is structurally possible has blossomed into a its first week of construction.
In the beginning we worked with the structural engineer and determined that the best design for the roof was to have the vegetated area cover 12’ wide sections on the support beams. Given the unique character of the planter like beds created by this design root barrier was added to the layered system.
After the design phase we helped the Sustainable South Bronx acquire materials for the roof and construction. Working with Sustainable South Bronx is always a real treat for us. Having helped train their initial in green roof installation crew, we have the joy of seeing old friends and the peace of mind knowing that the roof is in good hands.
Last week after some weather delays we were able to bring the growing media onto the roof and into its respective planting beds. It was a dirty job but somebody had to do it. Despite the gritty nature of the work it was visually relaxing seeing the roof begin to resemble a garden more than a roof.
This week the planting will be finished just in time for the plants to settle in and prepare for a long winter nap.
Once the roof is done a weather station as well as precipitation and temperature sensors will be added to monitor the green roof and regular roof.
This green roof will be open to the public for educational tours.
